How has 833 Sonora's energy performance changed over time?
BuildingCensus holds 2 California disclosures for 833 Sonora, covering report years 2023–2024. Its ENERGY STAR score went from 36 in 2023 to 13 in 2024 (-23 points); its best year on file was 2023, at 36. Site EUI moved from 82.5 kBtu/ft² (2023) to 113.2 kBtu/ft² (2024), an 37% increase.

What does an ENERGY STAR score of 13 mean?
ENERGY STAR scores run from 1 to 100 and are computed by the EPA's Portfolio Manager as a percentile against similar buildings nationwide, adjusted for climate, size and use: a score of 13 means the building performs better than about 13% of its national peers. BuildingCensus bands the score into report-card grades; 13 falls in band D — lowest band (1–54). It sits 62 points below 75, the threshold for ENERGY STAR certification. In California, 65% of scored buildings are at 75 or above.
Site energy-use intensity (EUI) is the energy a building uses on site in a year divided by its floor area, in thousand Btu per square foot — lower is more efficient. 833 Sonora's 113.2 kBtu/ft² across 90,605 sq ft works out to about 10.3 billion Btu (3,006 MWh-equivalent) in 2024. The disclosure also reports 2,642,740 kWh of electricity and 15,923 therms of natural gas for the year.
